Cylindrical member for cooling and heating

Abstract

A cylinder member for cooling and heating, comprising a plate-like profile body which is bent around the axis to form a cylinder shape; the two end faces of the plate-like profile body are fixed by welding; the plate-like profile body is provided with a fluid channel group formed by a plurality of through-holes which are arranged in parallel along the axial direction; the fluid channel group is formed with a fluid channel group inlet and a fluid channel group outlet, such that the member improves the cooling effect, facilitates processing, reduces the processing cost and material cost; under the condition of the same wall thickness, enhances the rigidity of the whole component by pulling corresponding profiles and using a simple bent plate mold can finish the processing.

1 . A cylinder member for cooling and heating, comprising:
 a plate-like profile body which is bent around an axis to form a cylinder shape,   wherein two end faces of the plate-like profile body are fixed by welding,   wherein the plate-like profile body is provided with a fluid channel group formed by a plurality of through-holes which are arranged in parallel along an axial direction,   wherein the fluid channel group is provided with a fluid channel group inlet and a fluid channel group outlet.   
     
     
         2 . The cylinder member for cooling and heating according to  claim 1 , wherein each one of the through-holes is formed with a through-hole inlet and a through-hole outlet,
 wherein the fluid channel group inlet is formed at one end of the plate-like profile body and communicates with all of the through-hole inlets,   wherein the fluid channel group outlet is formed at the other end of the plate-like profile body and communicates with all of the through-hole outlets.   
     
     
         3 . The cylinder member for cooling and heating according to  claim 2 , wherein a cross-section area of the fluid channel group inlet is equal to the sum of the cross-section areas of all of the through-hole inlets,
 wherein the cross-section area of the fluid channel group outlet is equal to the sum of the cross-section areas of all of the through-hole outlets.   
     
     
         4 . The cylinder member for cooling and heating according to  claim 1 , wherein each one of the through-holes is formed with a through-hole inlet and a through-hole outlet,
 wherein the through-hole inlet and the through-hole outlet are respectively formed at the two end faces of the plate-like profile body,   wherein the through-hole inlets and through-hole outlets of the adjacent through-holes communicate with each other,   wherein the fluid channel group inlet is formed at the through-hole inlet of the first through-hole,   wherein the fluid channel group outlet is formed at the through-hole outlet of the last through-hole.   
     
     
         5 . The cylinder member for cooling and heating according to  claim 4 , wherein the through-hole inlet and the through-hole outlet of each one of the through-holes are mutually staggered,
 wherein the through-hole inlets and the through-hole outlets of the adjacent through-holes are mutually aligned.   
     
     
         6 . The cylinder component for cooling and heating according to  claim 1 , wherein the fluid channel group inlet consists of two rows of through-hole inlets,
 wherein the fluid channel group outlet consists of two rows of through-hole outlets,   wherein the through-hole inlets are formed on the outer surface of the plate-like profile body,   wherein the through-hole outlets are symmetrically formed on the outer surface of the plate-like profile body opposite to the through-hole inlet.
